NON-REFILLABLE BOTTLE.

SPECIFICATION forming-,part of Letters Patent No. 781,041, dated l.T anuary 31, 1905.

Application filed February 2, 1904. Serial No. 191,726 v To al] whom, t may concern:

Be it known that I, ROBERT S. WIESENFELD, a citizen ofthe United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Non- Rellable Bottles, of which the following is a specification.

My invention relates to an improvement in non-reiillable bottles, the object being to provide a simple and inexpensive means for preventing bottle refilling; and the invention consists in a neck adapted to be secured to the bottle andretained permanently attached in connection with a valve and means for permanentlyretaining the valve in position with alimited movement which provides for emptying the bottle, but prevents its being refilled.

In the accompanying drawings, Figure l is a section. Fig. 2 is a bottom plan view of the valve. Fig. 3 is a detached view of the fastening-ring for retaining the valve in position within the chamber provided for it in the bottle-neck. Fig. 4: is a modification, and Fig. 5 is a detail view showing'the spring 10.

A represents a bottle, and B is the neck in-.

tegral therewith, while C is a separable neck litted thereto upon the ring 1, molded in the neck and offset from the part B of the neck, forming a shoulder 2. f Thel separable neck'C embraces this ring 1 and is rendered liquidtight by the packing 3 between its lower end and the shoulder 2. The outer surface of the lower end at least of the lseparable neck C is preferably flush with the surface of neck B, so that one appears to be a continuation of if not an integral part of the other. Y

The upper end of ring l1 forms a shoulder, as at 4:, and a valve 5, of inverted-cone shape,

having a flange 6 at the upper end', is supported by this iiange upon the shoulder orvalve-seatfi at the upper end of the ring 1. Thelower endof valve 5 is provided witha star 7, the points of which are adapted to center the valve by engaging and sliding upon the inner wall of the ring 1 as the valve moves outward or inward.

A fastening-ring 8 is provided with a circumferential groove 9 in its periphery, and a spiral band or spring 10 is adapted to fit in the groove 9 and a groove 11 in the separable neck, whereby to lock the fastening-ring 8 therein. Depending lugs 12 12 limit the outer vthe bottle.

movement of the valve,v insuring space between them for the discharge of liquid contents of 1t will thus be seen that the valveliange 6 and consequently the valve are confined in movement between the shoulder or seat 4 and the depending lugs 12 12.

The separable neck O may be locked permanently to the ring 1 by a spiral spring 13,

` retained in grooves 14 and 15 in the ring and separable neck, respectively, in a manner similar to that in which the fastening-ring 8 is retained in place.

The only difference in thev modificationV of consequence is that in lieu of a neck a ring 16 is molded directly upon the bottle similar to ring 1 of the construction just described, and the separable neck C', is this instance extends down to a shoulder 17 on the bottle adjacent to the ring, where a packing ringor gasket 18, similar to the onerS of the former construction, may be interposed between the separable neck and the bottle, the separable neck thus embracing' the entire ring and constituting the sole neck of the bottle.

Other slight changes might be resorted to, of course, in the form and arrangement of the several parts described without departing vfrom the spirit and scope of my invention,

and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what l I claim as new, and desire to secure by Letters Patent, isf The combination with a bottle-neck having a valve-seat formed at itsupper end, of an inverted-cone-shaped valve having a flange at the upper end adapted to rest upon the valveseat, and a star at the lower end which guides and centers the valve in the bottle-neck,.a separable neck,- a spring for locking the separable neck permanently to the bottle-neck, a

fastening-ring having an orifice therethrough andprovided with depending lugs,and a spring for permanently locking the fastening-ring in the mouth of the separable neck.-

In testimony whereof I aflix my signature in l presence'of two witnesses. ROBERT s. wIRsENEELD.
